Device for fastening a baseboard to a wall

ABSTRACT

A device is described for fastening a baseboard ( 8 ) to a wall ( 2 ) having a mounting profile ( 1 ) made of plastic, which forms a wall leg ( 3 ) and a receptacle web ( 7 ) for the baseboard ( 8 ), which is arranged offset transversely in relation to the wall leg ( 3 ) and has clamping ribs ( 10 ) extending in the web longitudinal direction. To provide advantageous structural conditions, it is proposed that the clamping ribs ( 10 ) be coextruded from a flexible plastic with the mounting profile ( 1 ).

FIELD OF THE INVENTION

The invention relates to a device for fastening a baseboard to a wallhaving a mounting profile made of plastic, which forms a wall leg and areceptacle web for the baseboard, which is arranged offset transverselyin relation to the wall leg and has clamping ribs extending in the weblongitudinal direction.

DESCRIPTION OF THE PRIOR ART

For fastening baseboards for floors, providing a mounting profile madeof plastic is known (EP 2 169 143 A2), which has a wall leg fastenableon the wall and a receptacle web for the baseboard, which is pluggedonto the receptacle web, which is offset away from the wall in relationto the wall leg and is approximately parallel to the wall. Thereceptacle web engages in this case in a receptacle groove of thebaseboard, which is fixed with the aid of clamping ribs provided on thereceptacle web. Because a nonlinear course of the wall has to beexpected, difficulties result when plugging the baseboard onto thereceptacle web of the mounting profile. As a result, longer sections ofthe baseboards require a greater allowance in relation to the engagementof the receptacle web in the receptacle groove of the baseboard providedfor this purpose in case of a nonlinear course of the wall, to be ableto plug the baseboard onto the mounting profile, while with shortersections of the baseboard, a sufficient clamp connection between thereceptacle web and the baseboard is endangered by such an allowance.

In order that a secure clamp of the receptacle web of a mounting profilein the receptacle groove of the baseboard can be ensured, bending thereceptacle web into the shape of a hairpin is additionally known (WO02/066764 A2), so that the two legs, which are each provided on theouter side with clamping ribs, of the hairpin-shaped receptacle webspring apart. The legs, which are pressed apart from one another under apre-tension upon insertion of the receptacle web into the receptaclegroove of the baseboard, therefore cause a springy contact of theclamping ribs on the walls of the receptacle groove and thus a tolerancecompensation. The plugging of longer sections of the baseboard inparticular onto a springy spread-apart receptacle web is in no wayfacilitated in the case of nonlinear courses of the wall, however.

SUMMARY OF THE INVENTION

The invention is therefore based on the object of designing a fasteningdevice for baseboards so that not only the plugging of the baseboardonto the mounting profile, which is fastened on the wall, is facilitatedindependently of the respective length of the baseboard section to beplugged on, but rather also a secure clamp connection, which issubstantially independent of the respective section length of thebaseboard, can be achieved between the mounting profile and thebaseboard.

Proceeding from a device of the type described at the outset, theinvention achieves the stated object in that the clamping ribs arecoextruded with the mounting profile from a flexible plastic.

Because the clamping ribs are formed from a flexible plastic, when thebaseboard is plugged onto the rigid receptacle web, they are pivoted viathe walls of the receptacle groove of the baseboard in the pluggingdirection toward the receptacle web with the effect that they providethe clearance required for the engagement of the receptacle web in thereceptacle groove of the baseboard to plug the baseboard onto thereceptacle web of the mounting profile in the case of a nonlinear courseof the wall. The clamping ribs, which are pivoted in toward thereceptacle web in the plugging direction as a result of theirflexibility, which is sufficient for this purpose, press in this casewith a friction lock against the wall of the receptacle groove of thebaseboard as a result of the intrinsic elasticity, so that theseclamping ribs have to be bent over in the withdrawal direction towithdraw the baseboard from the receptacle web of the mounting profile,which is accompanied by an increased deformation resistance andtherefore ensures a secure hold of the baseboard on the mounting profilein spite of the flexible clamping ribs. This is true in particular ifthe unloaded receptacle web including the flexible clamping ribs has athickness which exceeds the width of the receptacle groove of thebaseboard. Because the mounting profile is manufactured from asubstantially rigid plastic, the flexible clamping ribs can be producedin a comparatively simple manner jointly with the mounting profile bycoextrusion.

As a result of the intrinsic elasticity of the clamping ribs, a pressureforce is exerted via the clamping ribs on the walls of the receptaclegroove of the baseboard. This pressure force can advantageously beutilized to hold the baseboard in contact on the wall if the clampingribs made of the flexible plastic are provided on the side of thereceptacle web facing toward the wall leg.

To increase the withdrawal resistance of the baseboard from thereceptacle web, the clamping ribs can form clamping lips protrudingtransversely from the receptacle web, which have a width correspondingto at least twice the thickness, which facilitates the pivoting in ofthe clamping ribs toward the receptacle web upon insertion of thereceptacle web into the receptacle groove of the baseboard, but makesthe withdrawal of the baseboard from the receptacle web more difficultas a result of the width of the clamping ribs.

BRIEF DESCRIPTION OF THE DRAWING

The subject matter of the invention is illustrated by way of example inthe drawing, specifically a device according to the invention forfastening a baseboard to a wall is shown in a schematic cross section.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The device according to the invention has an extruded mounting profile 1made of plastic, which forms a wall leg 3 fastenable to a wall 2, whichis provided at longitudinal intervals with longitudinal holes 4 forfastening screws. The wall leg 3 protrudes from a bottom leg 5, which isconnected via an intended breakpoint 6 to the wall leg 3 and can beseparated from the wall leg 3 if needed. On the side opposite to thebottom leg 5, the mounting profile 1 forms a receptacle web 7 for thebaseboard 8 to be fastened on the wall 2, which has a receptacle groove9 for the receptacle web 7 for this purpose. The receptacle web 7, whichis offset away from the wall 2 in relation to the wall leg 3 and extendsapproximately in parallel to the wall 2 or to the wall leg 3, isprovided on the side facing toward the wall leg 3 with clamping ribs 10extending in the web longitudinal direction, which are formed in theexemplary embodiment as clamping lips protruding transversely inrelation to the receptacle web 7. These lip-shaped clamping ribs 10 areproduced from a flexible plastic, specifically by coextrusion with theessentially rigid mounting profile 1, so that the clamping ribs 10,which are formed from a sufficiently flexible plastic, can be pivoted inrelation to the receptacle web 7.

When the baseboard 8 is plugged onto the receptacle web 7 of themounting profile 1, which is fastened on the wall 2, the clamping ribs10 are accordingly pivoted by the applied wall 11 of the receptaclegroove 9 of the baseboard 8 toward the receptacle web 7, which isaccompanied by a tolerance compensation, on the one hand, and enables asubstantial compensation to a nonlinear course of the wall, on the otherhand, so that the baseboard 8 can be plugged in a comparatively simplemanner onto the receptacle web 7. The clamping ribs 10, which press witha pre-tension against the wall 11 of the receptacle groove 9 as a resultof the intrinsic elasticity thereof, ensure a good hold of the baseboard8 in spite of the flexibility thereof, because the withdrawal resistanceof the baseboard 8 from the receptacle web 7 is substantially greater incomparison to the plugging resistance as a result of the clamping ribs10, which are pivoted in toward the receptacle web 7 in the pluggingdirection. To withdraw the baseboard 8 from the receptacle web 7, theclamping ribs 10 have to be bent over in the opposite direction in thewithdrawal direction toward the receptacle web 7, which requiresovercoming a corresponding deformation resistance as a result of thewidth of the clamping ribs 10, which exceeds the distance of the groovewall 11 from the receptacle web 7.

In addition, the mounting profile 1 can be provided with a springylocking tongue 12, which latches with a hooked attachment into a catchreceptacle 13 of the baseboard 8 when the baseboard 8 is plugged ontothe receptacle web 7 of the mounting profile 1.
